Short for
Redundant Array of Independent Nodes,
RAIN is a data storage and protection system
architecture. It uses an open architecture
that combines standard computing and
networking hardware with
management software to create a system that is more distributed and scalable.
RAIN is based on the idea of linking
RAID
nodes together into a larger storage
mechanism. In a RAIN set-up there are multiple servers, each with disk drive and
RAID functionality, all working together as a RAIN, or a parity or mirrored
implementation. RAIN may also be called storage grid.
